How to measure for Otto Bock Derma Protection Knee sleeve.

STEP 2: Find your size

Take your knee circumference and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on safe side.

1 28-35.6
2 30-37.5
3 33-40.5
4 35.5-43
5 38-50.5

When measuring your thigh, pay special attention to how tight you take your measurement. It's best to pull the ends of your tape measure somewhat tight and then release. Your goal is to find a middle ground of how much tension you should apply to your measuring tape. Too tight and too loose will both result in a poorly fitting prosthetic sleeve.

Ottobock Harmony Knee Sleeve

The Ottobock Harmony Knee Sleeve is a prosthetic sleeve designed for moderate to highly active amputees who need a well-engineered sleeve. OttoBock constructed this sleeve with gel that combines softness, strength and elasticity. The Harmony sleeve offers complete freedom of movement and at the same time secure suspension by sealing with the skin without restricting circulation.

Installation is a breeze and cleaning is easy with Otto Bock Derma Clean. This below-the-knee suspension sleeve provides comfort and durability by incorporating an abrasion-resistant textile on the outside. Otto Bock includes a Gaitor sleeve protector with every sleeve. A Gaitor will protect your sleeve from prematurely wearing out from sharp prosthetic trimelines.


  • Harmony Sleeve is considered by many prosthetists as the industry gold standard in prosthetic sleeves
  • Covered with durable abrasion-resistant textile that works hard to prevent suspension and vacuum loss
  • Every Harmony Sleeve includes a gaitor sleeve saver in the box to protect your investment
  • Standard issue for users of Otto Bock's Harmony Vacuum System
  • Incredible vacuum sealing abilities
  • Sold each in polybag
